About IBAN Validator
The IBAN (International Bank Account Number) is a standard format for bank account numbers used across Europe and other countries. This tool validates IBAN numbers using the official mod-97 algorithm and generates valid test IBANs for development purposes.

- Format Detection: Automatically identifies the country and checks the length and structure of the account number (BBAN)
- Test IBAN Generation: Generates random IBANs with a valid format (national check digits included) for testing; they do not belong to any real account
